Witryna15 wrz 2024 · Three impurities were identified based on the molecular ion peak and their product ions. These impurities were synthesized and characterized using MS and nuclear magnetic resonance spectrometry. However, this method was unable to resolve the diastereomeric impurity, which is likely to be formed during synthesis. WitrynaThe reported optical purity for Eledoisin API was 94.7% while MS was 74.8% (the FDA drafted guidelines for synthetic peptides state that any impurity with 0.1% abundance 13 or higher relative to the API should be identified; the sum of impurity levels of an eligible drug product must not exceed 0.5%13).
